Prezi Charged Me Despite Cancelling Free Trial Early—Demanding Refund

I'm frustrated and disappointed because Prezi charged ₺ to my credit card even though I clearly canceled my subscription during the free trial period! I signed up for Prezi's trial offer, and I cancelled my subscription well before the trial ended. Yet, unbelievably, they still deducted money from my account! This is completely unfair and misleading—I canceled explicitly within the trial period to avoid exactly this issue. I've followed their cancellation policy precisely, yet they've ignored it and charged me anyway. Prezi needs to resolve this urgently by refunding the unauthorized payment immediately. Customers shouldn't have to fight to get their money back. Prezi, fix your billing system and honor your own terms—return my ₺ now, or I’ll escalate this further!
